JPH0245083A - Automatic direction converting and rising traveling device for one-wheel toy - Google Patents

Abstract

PURPOSE:To automatically execute directional conversion, rising and traveling by utilizing the centrifugal force of an outside case to be rotated and traveled with the movement of the center of gravity of a whole internal mechanism to accompany the activation of a motor in the outside case and reaction to accompany the change of a rotational shaft in a friction to execute high speed rotation in the internal mechanism. CONSTITUTION:When the automatic direction converting and rising traveling device of a one-wheel toy is set to fall sideways on a traveling surface and a switch is closed by a switch lever 10', a friction 1 starts rotation with the activation of a motor 7 and the motor 7 and friction 1 start high speed rotation with buzzing by coast. Simultaneously, this strong rotating force is transmitted to a friction gear 2, a first gear 3, a second gear 3', a third gear 4 and a main shaft 5 and the whole internal mechanism starts movement with the main shaft 5 as a center. In such a case, with the movement of the center of gravity in the whole internal mechanism, a semi-spherical protruding part 10 of an outside case 9 is contacted to the traveling surface and with this protruding part as a center, one part of a side surface in the lower side of the outside case 9 is also contacted and starts thr rotation just like the stopping time of a top. When the rotational shaft is changed by the same principle as a gyroscope, the strong reaction to this change is generated to the friction 1 to execute the high speed rotation. This reaction causes the whole device to rise up.

Description

[Detailed Description of the Invention] The present invention provides a method for preventing a one-wheeled toy from hitting an obstacle and preventing it from moving straight.
Or an automatic direction change or stand-up running device for one-wheeled toys that allows the toy to automatically change direction and run to avoid obstacles or automatically get up and run upright in the event of a collision and rollover. It is related to.

This invention relates to a specific example and a switch mechanism when using motor power, as described in the embodiment of the previous application (Patent Application No. 280034 of 1982).

To explain this invention with reference to the drawings, the internal mechanism includes a friction gear (1) and a friction gear (2) that are directly connected to a motor (7) at the bottom of a chassis (6). , a first gear (3) is provided to mesh with the second gear (3') fixed to the first gear (3), and a third gear (4) is provided to mesh with the second gear (3') fixed to the first gear (3). A fixed main shaft (5) passes through the upper part of the chassis (6) and is set so that both can freely rotate in conjunction with each other. At the left end of the main shaft (5), there is an outer case joint (11).
) is fixed, and is fitted and fixed into the joint hole (11') of the outer case (9). Also, a pipe-shaped switch (10) is fitted on the right side of the main shaft (5), and this right end passes through the center of the outer case (9), and a switch part is provided on the outside, and the outer side of the switch part is a hemispherical switch cover (1).
0"), and a pipe-shaped switch (1").
A joint plate is fixed to the joint of 0) to the chassis (6), and this connects to the joint pin (6') fixed to the chassis (6).
), the outer case (9) is fixed to the chassis (6) so that the entire switch part rotates in conjunction with the internal mechanism. It is constructed so that it can rotate freely inside.

In addition, the battery case (8') is fixed to the chassis (6) and the battery (8) is stored inside. Also, the wiring to the switch is connected from the side hole of the pipe-shaped switch (10) to the inside of the pipe and the main It passes between the shafts (5) and is wired to the switch part.

Further, in implementing the present invention, the switch mechanism can be operated not only manually but also remotely, such as by using a light sensor, using sound waves, using fireworks discharge, or using radio control. In addition, the motor (7) and the friction (1) can be connected by direct connection, or by connecting them via a spring, considering the space inside the outer case (9) and the center of gravity of the entire internal mechanism. It is also possible. In this case, the motor (7) can be installed relatively freely and there is plenty of internal space.

Further, as a method of transmitting power from the friction (1) to the internal mechanism, a belt drive is also possible in addition to a gear drive.

Regarding the battery replacement method, as shown in Figure 5, the switch cover (10'') can be opened and closed from the outside.
It is also possible to insert and load a small high-performance battery through the battery exchange hole (12). In this case, if the battery becomes too light and the center of gravity of the internal mechanism cannot be adjusted, it is recommended to add a balancer.

In addition, as shown in Figures 6 and 7, friction (1
) is made variable (in this case, belt driven) by the friction movable shaft (1'), and the rotation shaft of the friction actuating pin (1) and the actuating rod (14) are operated by radio control. ,friction(
It is also possible to perform radio control by tilting 1) left and right. Also, the operating rod (14) uses a lever, and the rotation axis of the friction (1) can be adjusted with a relatively small force. can be easily changed.

Also, there are various possibilities for the outer case (9), but
Various implementations are possible, such as transparent, opaque, partially transparent, etc., by covering the internal mechanism and making it into the form of a vehicle, such as a motorcycle or a rocket, on which a doll can ride.

Furthermore, the shape of the outer case (9) can be varied, such as the shape of an automobile tire or the shape of an oval diamond.

The automatic direction change and upright traveling device of the one-wheeled toy of the present invention is placed sideways on the running surface, and the switch lever (10') is
When the switch is closed, the friction (1) starts rotating as the motor (7) starts, and due to this inertial force, the motor (7) and friction (1) begin to rotate at high speed with a hum. At the same time, this strong rotational force is transmitted to the friction gear (2), first gear (3), second gear (3'), third gear (4), and main shaft (5), and the entire internal mechanism is The hemispherical protrusion (10''
) in contact with the running surface, and while also touching part of the lower side of the outer case (9), rotate around it, like when a top stops. Start.

In this state, the axis of rotation of friction (1) is changing, and the friction (1) rotating at high speed is
Based on the same principle as a gyroscope, changing the axis of rotation generates a strong repulsive force.

Friction (1) rotates in a circle around the main shaft (5) with the outside being low and the inside being high, similar to the above-mentioned "top" state.
Since the repulsive force of 1) is applied in the direction of raising the device body, the automatic direction change and standing up traveling device of the one-wheeled toy of the present invention gradually rises in a circular manner and gradually increases the rotation radius while standing upright. This means that it will start running.

As shown in Fig. 1, the friction (1) rotates in the direction of rotation (running direction) of the outer case (9), and in conjunction with this, the first gear (3) and the third gear (4). ), the main shaft (5) rotates in the direction of the arrow, and the outer case (9) rotates in the same direction as the friction (1).

For upright running, the entire internal mechanism is connected to the main shaft (
The outer case (9) is constantly suspended around point 5) due to the action of gravity, and the strong rotational power of the friction (1) is applied to the outer case (9), causing the outer case (9) to travel.

In this case, the repulsive force caused by the high-speed rotation of the friction (1) acts subtly against the direction of inclination of the outer case (9), causing the outer case (9) to run upright. For example, if the vehicle is tilted to the left in the direction of travel, a repulsive force will be applied to the friction (1) to change the direction to the left when viewed from above, and if the vehicle is tilted to the right, the friction (1) will act to change the direction to the right. For this reason, the bicycle does not fall over and rides upright, as if the bicycle's bundle had just been automatically cut off. Additionally, if there is a bump on the running surface, the resistance exerted on the rotation of the outer case (9) causes the entire internal mechanism to swing back and forth in the direction of travel, centering on the main shaft (5), causing the outer Even if there is a slight inclination that affects the running of the case (9), the repulsive force of the friction (1) will act accordingly, causing the outer case (9) to slightly change direction and move when it hits an obstacle. When the running of 9) stops, the outer case (9) starts to roll over, tilts a little, and at the same time the repulsive force of the friction (1) is applied, and the direction changes immediately according to the direction of inclination. It also changes direction. In addition, if the outer case (9) is tilted when the outer case (9) stops and the entire internal mechanism continues to rotate and rises to a position above the main shaft (5), gravity will act strongly and the If the vehicle completely rolls over, it will rotate in a circle, get up, and run upright, just like when starting up, depending on the width of the running surface and the presence or absence of obstacles. This device itself seems to have intelligence, as it repeatedly runs upright, changes direction, makes sudden turns, rolls over (which rarely happens), and gets up.

In addition, when stopping the automatic direction change and upright running device of the one-wheeled toy of the present invention, use the switch cover (10'') on the main body.
When you hold it in your hand with the side facing up, the entire internal mechanism rotates horizontally around the main shaft (5) inside the outer case (9), and in conjunction with this, the pipe-shaped switch (10)
is rotating as shown in Figure 4, and in this case, just by lightly touching the switch lever (10''), the switch will open and stop semi-automatically, making it extremely safe and secure to operate the switch. As mentioned above, we can provide toys that can be opened and closed, and that have dynamic movements that are very dreamy for children, as well as interesting and scientific toys that adults can also enjoy, and that are highly effective as science teaching materials. It is possible.
